I Application filed December 14, 1914. Serial No. 877,028.

To all wiiom it may concern:

Be it known that I, Roscoe P. BUFFING- TON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bottle-Seals, ofwhich the following is a specification.

This invention relates to improvements in bottle seals, and is especially adapted for use on milk bottles.

The object of the invention is to provide a seal. which can be used upon the bottles in general use, i and which when opened forms a pouring lip which prevents the contents of the bottle from coming into contact with the lip, or any exposed part, of

the bottle.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and.

pointed out in detail in the appended claims. In the accompanying drawings, Figure 1 is a perspective view of'a milk bottle in a tilted position, showing my invention applied thereto. Fig. 2 is a vertical section of Fig. 1. Fig. 3 is a verticalsection of a bottle with the seal in its normal position. Fig. 4 is a similar View to Fig. 3, showing the paper sealing disk being raised. Fig. 5 is adetail plan view of the seal. Fig. 6 is an edge view of Fig. 5. Fig.7 is a detail view of the staple which secures the two disks together.

In the accompanying drawings, forming,

part of this specification, and in which like reference numerals designate like parts through the several views, 1 .designates a bottle showing an annular shoulder 2 on the inside of the mouth thereof and upon which the bottle seal rests. The said bottle seal con'lprises a disk 3 made of heavy paper, or other suitable material, and having a pouring aperture l near the center thereof and an air vent 5. Secured to the upper surface of the disk 3 is another disk 6 having a piece 7 at the edge thereof and by means of which the disk 6 is pulled back and away from the disk 3 far enough to uncover the apertures 4t and 5 and to allow the raised portion of the disk 6 to fold back over the lip of the bottle. The disk 6 is secured to the disk 3 by the staple 8 andisp'rovided rnrc.

with a. coating of paraffin, or similar substance, so that it adheres to the disk 3, thus securely covering and sealing the apertures 4t and 5. The staple 8 is just back "of the pouring aperture 4 so that the'disk 6 will fold in a lineclose to said aperture 4 in order that the contents of the-bottle will flow through the aperture 4 and over the folded portion of the disk 6.

When it is desired to pour the contents,

or part thereof, it is only necessary to pull the disk 6 up from the disk 3 by means of the finger piece 7, as shown in Fig. 4:, causing it to fold back in the position shown in Figs. 1 and 2, uncovering the aperture 4 andthe air vent 5. disk 6 which is raised is folded over the lip of the bottle. The bottle is then tilted allowing the contents to flow through the aperture 4 and over the disk 6, thus preventing the The portion of the said contents of the bottle from coming into a contact with the lip, or any exposed portion, of the bottle. If only a portion of the contents of the bottle is removed therefrom the disk -6 can be folded back upon the disk 3 covering the aperture 4 and the air vent 5, thus preventing the dust or, other particles from falling into the bottle.

Having thus described my invention, what I claim is:

1. A bottle seal comprising a disk having a pouring aperture near the center thereof and an air vent therein, a second disk resting upon the entire upper surface of the firstnamed disk and adapted to cover the said aperture and air vent and having an in-' tegral piece projecting from the edge thereof, anda staple projecting through both disks adjacent the pouring aperture to allow the upper disk to fold close to said pouring aperture.

2. The combination with a bottle having an annular shoulder on the inner surface of the mouth thereof, of a seal comprising a disk fitted within the mouth of the bottle and resting on said shoulder and having a pouring aperture near the center thereof and an air vent therein, *a second disk resting upon and covering the entire upper surface ofthe first-named disk and having a portion thereof adapted to fold back over the lip of the bottle, seid second disk hav- In testi inony whereof'I aflix my signature ing a piece projecting from the edge thereof, in presence of two Witnesses. o and a staple passing through both disks ad- ROSCOE P.
